Vijay commented on CASSANDRA-3722:
----------------------------------
How about instead of sending gossip message, in DES.updateScores we can also
compare the number of waiting tasks to be performed on a given node, this way
we can actually move on to the next node when there is a lot more pending data
to be received before receiving the latencies... Makes sense? (Where pending is
node y pending > (another node x 's pending + %) the prefer the node x)
> Send Hints to Dynamic Snitch when Compaction or repair is going on for a node.

> URL: https://issues.apache.org/jira/browse/CASSANDRA-3722
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.1
> Reporter: Vijay
> Assignee: Vijay
> Priority: Minor
>
> Currently Dynamic snitch looks at the latency for figuring out which node
> will be better serving the requests, this works great but there is a part of
> the traffic sent to collect this data... There is also a window when Snitch
> doesn't know about some major event which are going to happen on the node
> (Node which is going to receive the data request).
> It would be great if we can send some sort hints to the Snitch so they can
> score based on known events causing higher latencies.
